The Integra M series (450w, specifically) looks like a good PSU for the price. You mentioned in your list that it should not be put into high end systems. As I upgrade my computer, what would be the point where I should switch out the PSU? I know I have a budget build, but I have heard people refer to even some FX CPUs as "high end." If I want to upgrade in the future, is the Integra M series a smart choice or a bad one?
I wouldn't put anything above a 380 on AMD's side or a GTX 970 in there on Nvidias side
